DotNet / Re: Vertex Or Sprite Batching in Csharp

« on: June 01, 2023, 11:28:47 pm »

I'm thinking of making everything a sprite , then cycle trought all of them every frame then put it into a vertexarray , but i dont know if it is a good idea ,

VA = new VertexArray();
foreach(sprites){

vertex = new Vertex();
vertex.position = sprites.getPosition();
vertex.texture.position = sprite.GetTexturePosition();

VA.AddVertex(vertex);
}

window.Draw(VA,Renderstates);

something around those lines would work i think.

DotNet / Vertex Or Sprite Batching in Csharp

« on: June 01, 2023, 10:48:51 pm »

I'm trying to do a hell-bullet game , so more than maybe 2000-5000 entities in the screen but i can't find a good way to do batching.

I found some c/c++ code to make SFML batching but i'm no genius so i dont understand how to translate it into C# code !

Others things the documentation show off some C++ way to extend SF::Drawable and SF::Transformable.

I can't find C# documentation , if anyone could tell me how to batch eitheir Vertex or Sprite in C# in a good way.

As of now the vertex batching i made , make it hard to apply rotation or animation , when I apply rotation to a renderstates it make my vertex texture dissapear i don't know why !

I'm ready to pay for some help if anyone has clue on how to fix this  in C sharp , her my discord :: https://discord.gg/srzchsKDEq

Graphics / Re: Vertex Texture and Vertex Color not working in C#

« on: March 19, 2023, 09:04:57 pm »

After Looking at others question on the forum i found out that  some Vertex constructor put Vertex.Color to White.  So it seems that white color do little or no effect on the texture . Have a nice day !

Graphics / Vertex Texture and Vertex Color not working in C#

« on: March 19, 2023, 06:27:23 pm »

Hi , i can't find out how to use Vertex  Texxcord in c# without using vertex.Color ! which is slightly modifying the images color !

i saw this page : https://www.sfml-dev.org/tutorials/2.5/graphics-vertex-array.php in C++ but it seems to behave differently than C# equivalent.

I cant draw/render  unless i use a color on my vertex , i dont know why ! Any clue is appreciated !
